SHADE-HOLDING MIEANS FOR ELECTEIG FIXTUEJES.

Application filed September 18, $913.

To (ZZZ whom 1' t may concern Be it known that I, Lacuna Annunsrx, a citizen of the United States, residing at lVaterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Shade- Holding Means for Electric Fixtures, of which the following is a specification.

This invention relates generally to electric light fixtures and more particularly to a portable lamp fixture.

The portable fixture to which my invention is particularly adapted embraces in its construction a suitable support for the incandescent lamp socket and in connection with this support is employed. a shade or re flector which shade or reflector is pivotally connected to a shade holder which is adapted to the-socket support.

In the port-able lamp to which my invention is particularly adapted the socket support has comprised a ball joint as a part thereof so that various adjustments could be obtained and in COIlIlQCtiOIl'Wltll the shade 'or reflector the light could be directed in in providing a rotatably adjustable shade holder or support upon the lamp support and in providing frictional means for holding said shade holder at any desired point of adjustment. The invention consists also in certain-de-- tails of constructionhereinafter fully described pointed out in the claims.

Inf'the drawings forminga part of this specifications-Figure 1 is a perspective View of a portable lamp embodying my invention, the shade holder being shown in one adjustment and, Fig. 2 is a similar'view showing the shade holder adjusted to a ditl'erent position. if" g. is an enlarged view of the frictional holding means. d is a detail sectional View, and, 5 is a Specification of Letters Patent.

Eeferring to the drawings A indicates a pedestal or support which comprises in its construction a ball joint B such as shown and described in my application for patent filed September 6, 19123, Eterial Number 788,4:18, patented December 2, 1913, Near bcr resales.

Connected to the pedestal or support is the lamp socket C, this socket being of any desired or approved construction. in connection with this portable lamp I employ a shade or reflector D which is pivotally conplate F, the ends F of which bent back and under and are adapted to contact with the central portion of the shade holder this plate'beiug of such size, shape and construc tion as to provide suflicientfrictional contact between the parts so that the shade or reflector holder can be rotated upon the support but will be held at any desired point of adjustment. This is a very important feature when taken into combination with the adjustment of the ball joint in the support and the shade or reflector adjustment upon the holder, as by making the holder rotatably adjustable and locking the same iirictionaily at any desired point of adjustment? able to adjust the shade or reflector any point it may be deemed necessary in order to direct the rays of light in. the proper direction.

hide I have shown and described my invention as applied to a portable lamp, it will be understood that the invention is adapted for use in connection with other forms of fixtures so long as the rotatable sb de or reflector holder is rotatably mountupon the socket support.

What it claim is The combination with a support comprising a ball joint as a 'tliiereon shade holding bracket arzran 'ed upcn sai. anyport and adapted to mm thereon, a spring friction plate arranged also upon said support, 2v socket arranged upon the end said support and adapted to maintain the sprhlg friction te in Contact with Zhe shade helder bra' zet, ccmbined Shane 59 XS. 500m, B.
